A marine propulsion device includes a controller configured or programmed to perform a control to suppress an engine rotation speed. The controller is configured or programmed to perform an initial misfire control to determine whether or not a cylinder of the engine is caused to misfire in order to suppress the engine rotation speed when it is determined that an initial sudden increase in the engine rotation speed that causes over-revving has occurred based on a detection result from a rev-up detector, and perform a subsequent misfire control to determine whether or not the cylinder is caused to misfire in order to suppress the engine rotation speed when it is determined that a subsequent sudden increase in the engine rotation speed that causes the over-revving has occurred following the initial sudden increase in the engine rotation speed based on the detection result from the rev-up detector.
